Mild acidic pH inhibition of the major pathway of herpes simplex virus entry into HEp-2 cells.

Penetration of the KOS strain of herpes simplex virus type 1 (HSV-1) and the MS and 333 strains of herpes simplex virus type 2 (HSV-2) into HEp-2 cells at pH 6.3 was at least 100-fold less efficient than at pH 7.4. Penetration of two low passage…

Oxygen consumption after massive sympathetic nervous system discharge.

We evaluated the possibility that massive, sympathetic nervous system (SNS) activation [as may precede the development of neurogenic pulmonary edema (NPE)] increases O2 demand. O2 consumption (VO2) and plasma concentrations of the calorigenic agents,…

Effect of elevated vascular pressure transients on protein permeability in the lung.

Neurogenic pulmonary edema (NPE) may develop in individuals with head trauma or seizures and is generally thought to have a hydrostatic basis in the severe degree of pulmonary hypertension that occurs. Recently, it has been suggested that vascular…

The antinociceptive effects of 3,4-methylenedioxymethamphetamine (MDMA) in the rat.

The antinociceptive effects of MDMA and morphine were examined in rats using the tail-flick and hot-plate analgesiometric tests. MDMA, in the dose range of 1.5-6.0 mg/kg IP, produced a dose-dependent elevation in hot-plate latency, but did not…

Spinal beta-endorphin analgesia involves an interaction with local monoaminergic systems.

beta-Endorphin administered intrathecally (i.t.) in rats produced a dose-dependent elevation in tail-flick latency. Naltrexone administered i.t. as a pretreatment reversed the spinal antinociceptive action of beta-endorphin, suggesting that the…
